I kindof figured that out in 2004, when my combo went 32mpg with an 1850 that I leaned on strictly for hiway cruising with no real tuning, just threw something at it, to see if it would stick. Ima thinking it couldda done even better. Course nobody buys 32 mpgs on a 367 HO engine, so most of the time I keep it to myself. I can't speak to 100mpgs tho,lol
